Abstract
An always-on display method includes, in response to a screen-off event, a first processor sends always-on display control information to a second processor and then sleeps. The always-on display control information includes an always-on display instruction. In response to the always-on display instruction, the second processor switches a screen-on interface to a first screen-off interface, and in response to a screen-off interface switching event, the second processor switches the first screen-off interface to a second screen-off interface, and the display content of at least one of the first screen-off interface or the second screen-off interface includes a dynamic picture.
Claims16
An always-on display method implemented by a terminal device, wherein the always-on display method comprises:
- responding to a screen-off event by:
- sending, by a first processor of the terminal device, always-on display control information to a second processor of the terminal device, wherein the always-on display control information comprises an always-on display instruction;
- and
- entering, by the first processor, a sleep mode after sending the always-on display control information to the second processor;
- and
- controlling, by the second processor in response to the always-on display instruction, a screen-off interface of a display screen of the terminal device by:
- switching, by the second processor, a screen-on interface to a first screen-off interface;
- switching, by the second processor in response to a screen-off interface switching event, the first screen-off interface to a second screen-off interface, wherein first display content of at least one of the first screen-off interface and the second screen-off interface comprises a multi-frame animated picture;
- determining, by the second processor according to a first always-on display rule, the first screen-off interface;
- and
- determining, by the second processor according to a second always-on display rule, the second screen-off interface,
- wherein the first screen-off interface is a black screen interface,
- wherein the first always-on display rule comprises controlling the display screen to keep black continuously,
- wherein the second screen-off interface comprises a first interface and the black screen interface,
- wherein second display content of the first interface comprises the multi-frame animated picture, and
- wherein the second always-on display rule comprises switching to the black screen interface after the first interface is displayed for a predetermined duration.
A terminal device comprising:
- a display screen comprising a screen-off interface and configured to obtain a screen-off event, wherein at least one interface in the screen-off interface comprises a multi-frame animated picture;
- a first processor coupled to the display screen and configured to:
- in response to the screen-off event, send always-on display control information, wherein the always-on display control information comprises an always-on display instruction;
- and
- enter a sleep mode after sending the always-on display control information;
- and
- a second processor coupled to the first processor and the display screen and configured to:
- receive the always-on display control information;
- and
- control, in response to the always-on display instruction, the screen-off interface by:
- switching a screen-on interface to a first screen-off interface;
- switching, in response to a screen-off interface switching event, the first screen-off interface to a second screen-off interface, wherein first display content of at least one of the first screen-off interface and the second screen-off interface comprises a multi-frame animated picture;
- determining, according to a first always-on display rule, the first screen-off interface before switching the screen-on interface to the first screen-off interface;
- and
- determining, according to a second always-on display rule, the second screen-off interface before switching the first screen-off interface to the second screen-off interface,
- wherein each of the first screen-off interface and the second screen-off interface comprises a first interface and a black screen interface,
- wherein second display content of the first interface comprises the multi-frame animated picture, and
- wherein both the first always-on display rule and the second always-on display rule comprise switching to the black screen interface after the first interface is displayed for a predetermined duration.
